One might use SDL audio, the other not. And the one or other might or
might not work with your system.
mame has an option -audiodriver.
Try in either mame
mame -audiodriver alsa
on the command line. The other options besides "alsa" might be "sdl" or
"oss". If one works you can set it up in /etc/mame/mame.ini .
